l Application To all whom t may concern:

Be it known that I, EDGAR C. WiLiiY, a. citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Radiator-Valve, -of which the following is a specification.

l This invention has reference to improvements in radiator valves, and its object is to provide a valve for the purpose which may be readily adapted to diiferent radiator c apacities, so that a single size of valve will answer for many different sizes of radiators.

In accordance with the present invention the movable member of the valve is so constructedy that it may be fully opened or fully closed by a short movement of the customary handle, and it is desirable that this movement should not exceed an arc of more than about one hundred and eighty degrees, while a fractional rotation of the valve stem loetween tlie two extremes causescorresponding graduation of the supply. With such a valve steam or other heating fluid may be admitted to the radiator in large or small quantities tov suit weather conditions, and this is accomthe valve stein accord- Vifhere a lever handle is provided it is customary to arrange the opening and closing movement of 'the valve so that when the lever handle stands away from the radiator the valve is closed, and when it stands toward the radiator the valve is fully open, thus apprising the olis'eri er at a glance as to whether the steam is turned on or oit, and by a suitable index fractional positions are read-- ily indicated. In addition to this graduat-V ing function of the-valve, the present invention contemplates an independent adjustment whereby the caliber of the steam port, assuming the valve to be a steam valve, may be permanently adapt the valve to a large or a small radiator, this being equivalent to making the valve largey or small to meet the requirements small radiators, but bringing this desirable condition about with a single size of valve. This avoids the necessity of carry` ing the valves in a multitude of sizes. It is impossible to determine just thel proper size radiator, as this will varv with the pressure-and othercondietc., resulting Specification of Letters Patent.

from the proximity to or remotenessof the radiator fromthe boiler or other. source of supply. In practice it is found necessary in Aorder to get accurate results, to adjust the caliber of the valve to the radiator under practical working conditions after fit 'is installed, and suchpermanent adjustment must be made in such away `uating action of the valve is maintained throughout the arc of the handle movement, Whether such permanent adjustment be made for a large or a small radiator, and, moreover, it is desirable that the lever movement be always the same plied to a large or a small radiator.

thatv the gradwhether the valve is ap-- In accordance with the present invention the opening and closing, movement of the valve with respe t to theiport it controls is constant for? all sizes of` radiators to which the valve is adapt-ed, but .the permanent adjustment is brought about by the employment of an auxiliary Calibrating plug carried by the movable member of the valve and so related thereto that it can be adjusted -with relation to the steam port to vary the same.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanyingdrawings forming a part of this specification, with the further understanding that While the drawings show a practical form of the invention, the latter is not confined to` any strict conformity with the showing of the drawings, but may be changedand modified so long as such changes and'modiiications mark no materialdeparture from the salientfeatures of the invention.

In the drawings-#Figure 1 is a longitudinal`diametric section of the valve with some parts shown in elevation. Fig. 2 is a plan view of the valve structure. Fig.'3 is a fragmentary section of a portion of the valve as shown in Fig.-1, but showing -the movable member of the valve in the open position. Fig. l is a view similar to Fig. 3 butsliowing a diiferent position of the calibrating plug from that shown in Fig. 3. Fig. 5 is a detail section on the line 5-5 of Fig. 1,-distant partsV being omitted. Fig. i's a view similar to Figi, showing another form of valve operating mechanism.

Referring to the rawingsthere is shown a valve casing 1 provided Withangle necks 2,

ioo'y 3, respectively, suitably threaded for attach ment to a steam pipe and to a radiator. Ad* jacent to the neck 2 thev casing l isforined with an interior web 4 having a port or passage 5 therethrough terminatin at the end remote from the neck 2 ina taring valve seat 6. The portion of the casing 1 remote from the neck 2 is formed into an interiorly threaded neck 7 for the reception ot a bonnet 8 having a hollow axial extension 9 provided with interior screw threads 10 of long pitch. The bonnet 8 is provided with a cavity 11 designed for the reception of packing 12 and adapted to the bonnet so as to engage the.

packing 12 is a packing gland 13 on which is formed a radially extended dislclike flange packing 12, and axial extension 9 is a tubular` valve stem 18 laterally enlarged and threadl 14, while the corresponding end of the bonnet 8 is formed with a radial iiange 15 to which the disk-like Hange or disk 14 is secured by a screw 16 passing through the disk 14 and threaded into the fiange 15 and provided with a. head 17 having a purpose to be described. `Extended through the gland 13,

ed, as indicated at 19, to match the `screw threads 10 and terminating. within the casing 1 in a valve head 20 formed `with a counterbore 21 in alinement with the bore ot the tubular stem, the head 2() having a terminal portion 22 shaped to ft the valve seat 6. The valve stern 18 has the end passing through the gland 13 extended beyond the latter and also counterbored and internally threaded, as indicated at 23. The terminal portion of the last-named extended part of the valve stem is exteriorly threaded, as shown at 24, to lreceive a cap nut 25, and adjacent to the exteriorly vthreaded portion 24 the extended portion of the valve stem is `exteriorly serrated, as indicated at 26, to receive a similarlyserrated boss 27 on a lever 28 having a short nose extension 29 on one side of the boss 27 and a stem 30 on the other side of the boss, said stem carrying a manipulating handle 31 which `may be formed of wood or some suitable substance of small heat conductivity and shaped to be readily grasped by the hand of the operator. 4The serrated portions 26 and 27 permit the placing of the manipulating lever upon the valve stem in' the desired position Within very close adjustment and the nut 25 serves to hold the lever or handle to the valve stem against accidental removal.

Extending lengthwise through the hollow or tubular valve stem 18 is a rod 32 extending into the threaded portion 23 of the valve stem 18 and there screw threaded, as indicated at 33, to fit the interior threads of the portion 23, the corresponding end of the rod 32 being notched. as shown at 34, or other- Wise suitably formed for the application of a tool whereby the rod 32 may be screwed along the valve stein 18`where the part 33 enbolic in shape.

gages in the threaded bore 23. At the other end of the rod there is secured thereto a plug axially inset into the plug` as shown, or any other means may be provided for the purpose. The plug is of such diameter as -to enter the port 5 and also enter into the counterbore or chamber 21 in the valve head 20, and the plug may be drawn into the chamber 21 to any desired extent by turning the rod 32 about its longitudinal axis, the "screw threads of the end 33 and within the counterbore 23 coacting to cause the longitudinal movement of the rod 32.

The plug 35 is shown as frusto-conoidal in shape and ,may quite closely approach a parabolic form in longitudinal section. The greatest diameter of the plu is very nearly the same as the diameter o the port 5, which latter is of circular or cylindrical shape in the showing of the drawings.

It is advantageous from a manufacturing standpoint and'economical for the installation of steam or hot water heating plants to have the controlling valves all of onesize irrespective of the size of the radiators employed, and it is further highl advantageous to have the controlling va ves so that a single valve may be readily adjusted to properly control the uid supply to the ra` diators irrespective of their capacity.

One size of valve made in accordance with the present invention will supply a large radiator, say, one of one hundred and fifty feet radiating surface, or a small radiator, say, one of five feet radiating surface, with substantially equal efficiency throughout the range of adjustments from fully closed to full open positions, in accordance with the adjustment of the Calibrating plug. This is due to the shape of the Calibrating plug and its relation to the port controlled by the main valve, as well as the shape of the port. It is of importance that'the port where it coacts with the calibrating plug be straight or cylindric;.ll 4while the plug itself has at its larger end a very slight taper within the range of movement of this part of the plug with respect to the end of the port it enters when the plug is in the `35, a screw 36 passed axially through the the plug toward the smaller end thereof.

the` taper is progressively greater, so that the'jplug .issubstantially conoidal or ara- TheA result of this is that considering the plu-g 35 as in its full projected osition, it begins on the op'eningof the va ve to supply steam in progressively increasing quantities as the valve moves toward thefully open position, until when the last-named position is attained the steam supply is that suited to a five foot radiator, considering such a radiator as of the niinimum size for which the-valve is designed. Moreover,.the slight taper of the plug as it moves through the port 5, and more particularly that end of the port where it joins the valve seat 6, regulates the supply of steam, so that such supply shall be in progressively increasing quantities as the valve opens conforming to the degree of opening of the valve. It, now, the plug be drawn into the` valve heady 20, say, to anextent to correspond to a fifty foot radiator, then the taper of the walls of the plug 35 with relation to the outlet end of the substantially cylindrical port 5` is such as to supply steam proportionate to the opening of'the valve until at fully open .position the steam supplied is suilicient ora valve and with the Calibrating plug fully drawn into the head Q0, the supplyof steam provide the saine proportionate amount of drawings convey user by the words Hot7 and Cold that fully open or fully closed,`

The valves may be adjusted before installation to an approxima tion of the proper adjustment, and then 4after installation each valve is more accu'- rately adjusted by removing the cap nut 25 andturning the stem 32 ot the calibrating plug 35 by means of a screw driver, thus projecting the Calibrating plug or withdrawing it into the head 20, as the case may be. Such operation is needful to bring the valve into proper final adjustment, ,but when once this adjustment is attained a half .revolution of the operating handle means the full opening or the vful closing of the valve irrespective of the size of the radiator, and

furthermore intermediate positions of the handle mean that the radiator is receiving the proper supply of steam for the particu'- lar size of radiator to which the valve has been adjusted by the longitudinal movement of the Calibrating plug Aplug with respect vtion to the port 5 fifty foot radiator` without appreciable Waste'.

The Calibrating plug does not close the steam supply, but regulates it and the peculiar re very close approach to accuracy in the supply 'ot' steam for the radiator to which the valve is adjusted by the same degree of turning of the valve handle for any or all sizes of radiators. mentso the valve aside from the calibrating plug are the same for all radiators, while the adjustments of the Calibrating to its position with ielasupply of steam for radiators of different sizes, while the proportionate supplies irrespective of the size of the radiator vfor the different positions of thevalve are automatically accomplished by theshaping of g5 the Calibrating plu-g or head with respect to the port 5-and also the shape of the latter.

Experience has shown that the port 5, or at least that portion of it coacting with the calibratin plug, is, it shal neither taper nor diverge where in coactive relation with the plug 35, `and this plug must taper very slightly at its 'large end andthen more rapidly toward its parabolic 95 small end, sothat the conoidal or form is either attained' or very closely approximated.

instead ot' employing the type ot'valve 110 shown in Fig. l. and' associated figures, where the stem ot' the main valve has the operating handle directly connected thereto, tliestructure may be made on the lines of the socallcd packless valve, as shown in Fig. 6. In 115 this construction there is a valve casing 1 which may be in substantially all respects similar to the structure shown in Figfl, and this rasin'g carries a bonnet 8 provided with a skirt 9 within the chamber 11 at that end of the bonnet remote from the skirt 9a. The bonnet is pro vided with an outstanding liange 15 similar to thel flange 15 otthe structure of Fig. 1,

and this `fiange'carries a plain disk 14;a se- 125 cured thereto by a screw 16n having a head 17 as in the structure ot Fig. 1. A handle lever QS/iitthe main similar to the lever 28 o f Fig. 1 is provided and this handle has a' hub portion 27 of lation of the calibrating plug 35 and port 5 brings about a j() This means that the movebrings about the proper 30 must be cylindrical, that of the valve structure, hasfits casing- 1` and with a 120 an axiallength to extend 13o thro-ugh the\\disk 14a into the chamber 11a where it is engagedby a spring 38 bearing at one end agalnst 'the inner end of the chamber 11 and at the other end against the natinfr in an exteriorl f threaded iortion 19 counterbored or enlarged, as indicated at 40. That end of the tubular stem 18 remote from the threaded end 19a extends through the hub 2T and beyond the same where it is exteriorlyl threaded, as indicated at 2&2 to receive a cap 25 which in the main may be similar to the cap 25 of Fig. 1 and moreover, the stem 18et where encircled by the hub 27 may be toothed or serrated, as indicated vat E26, similarly to the like parts of Fig. 1. Within the ca sing 1 is a hollow valve head 2Oa having an internalvchamber 21 a'nd an engaging end 22a adapted to the valve seat 6 of the casing 1 about the port 5. The

valve head 20a is providedat the end remote from the engaging portion 22 with a hollow extension 41 interiorly threaded for the reception of a threaded end 19 ot' the stem 18?V The valve head 20a has an intermediate interior web 42 axially threaded for the passage of a threaded portion 430i a stem 32 which enters the ystem 18a and extends throughout the greater portion of the length thereof, this stem having at the end remote from the threaded' portion 43 a notch 34 for the reception. of a ananipulating tool and rendered accessible on the removal of the cap 25a. The stem 32a at the end adjacent the screw-threaded portion 43 carries, or has formed thereon a plug 35 which may be similar to the plug 35 of Fig. 1 and performs the same function. The Space inclosed b v the skirt 9 may be'of non-circular cross-section and the portion lil of the valve may conform to the interior of the skirt, so

that the valve may be moved lengthwiseV without turning by ak turning movement of the stem 18, the meshing of the threaded portion 19a withI the threaded portion 4,1 bringing this movement about. Where the stein 1,18 entersthe skirt 9g it is formed with an exterior flange 44 bearing against a. packing ring 45 lodged in the corresponding part of the bonnet, and this flange is maintained in contact With the packing ring by the expansive action ofthe spring 38. The stem of the plug 35a is maintained in any adjusted lrelation to the valve QOFby the threaded connection 43 and participates in all movements oi the valve, the stem 32 sliding lengthwise With the stem 18,1so that the same'result is brought'aoout by the structure of Fig. (S as is accomplished by the structure of Fig. 1, the principal differences being in the packing arrangements and the variations 1n struc-v ture causedby the changed packing. The

plug 3Va may be in one piece with the stem 39. or may be separate therefrom and con` nected thereto as indicated in Fig. 1.
